10/100 Mbit/s twisted pair connection on MM22-T1T1T1T1
PoE media module
10/100 Mbit/s ports (RJ45 sockets) allow the connection of terminal
devices or independent network segments according to the IEEE 802.3
100BASE-TX / 10BASE-T and IEEE 802.3af (Power over ETHERNET on
data lines) standards. These ports support:
Autonegotiation
Autopolarity
Autocrossing (if autonegotiation is activated)
100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
10 Mbit/s half-duplex mode, 10 Mbit/s full duplex mode
Power over ETHERNET
Delivery condition: Autonegotiation activated except for the ring port: 100
Mbit/s, full duplex. The socket housing is electrically connected to the
front panel. The PoE voltage is fed in via pins 4&5 and 7&8 (spare pins).
